' LINE-PAINTING MAGHINEQ Application filed December 11, 1924, Serial No. 755,229. Renewed February 4, 1 926.

In the control of traflic it isc-ustomary to provide lines upon the highways and streets generally,such lines belng broad and painted upon the surface so as to wlthstand usage. These lines are usually painted upon the surface by hand with the result that they are maintained at some considerable expense in addition to the original cost for labor.

In accordance with the present invention a machine is provided and adapted to be traveled over the surface and automatically paint the lines thereon, said -machine embodying a container or reservoir for holding the paint in bulk, a rotary brush for applying the paint to the surface and distributing means for controlling the flow of the paint fromthe reservoir to the brush,

the latter being detachable to admit of cleaning when not required for immediate use.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be, understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing fromthe nature of the invention.

Referring to the accompanying drawings forming a part of the specification,

Figure 1 is a side view of a line painting machine embodying the invention,

' Figure 2 is a top plan view of the machine,

Figure 3 is a sectional view on the line 3-3 of Figure 2,

Figure 4 is a detail view on the line 4-4 of Figure 3, v

Figure 5 is a detail sectional view on the line 55 of igure 3, and v Figure 6, is a detail sectional view on the line 66 of Figure 3.

Corresponding and like parts are referred to in the following description and designated in the several views ofthe drawings by like reference characters.

The machine embodies a suitable frame 10 which is mounted upon ground wheels 11,

belt 15 connects the pulley 14 with the pulley 16 fast to an axle 17, upon which is mounted a rotary brush 1 8. The crossing of the belt 15 results in rotating the brush 1 8 in a reverse direction to the ground wheels 11,with the result that the, brush tends to resist the speed and to positively apply and spread the baint. V

A reservoiror container 19 is mounted upon the frame 10 and holds the paint to be applied to the surface when lining the same. A pipe 20 connects with the lower portion of thereservoir 19 and is provided in its length -with a controlling valve 21 which is at all times under control vof the operator by means of arod 22 which extends within convenient reach of the grip of the handle 13. A distributor 23 is connected with the pipe 20 and delivers the paint to the brush 18 and this distributor is formed with outwardly flared sides and with a top and bottom arranged with a restricted opening therebetween, and having grooves in its bottom to direct the paint to the surface of the brush. A catcher 24 is provided to receive surplus paint and prevents the same from dropping upon the surface. Plates 25 are applied to opposite sides of the brush to prevent spreading thereof and to prevent waste of paint and insure the formation I of I a line of uniform width. The drip catcher 24 connects the guard plates 25 in the rear of the brush. Hangers 26 are connected at their lower ends to the guard plates 25 and are adj ustably connected to the frame 10 by means, of a rod 27 or like part. In this manner the brush 18' may be elevated and the removable feature of the axle 17 admits of the brush 18'being detached for cleaning or placed in a vessel containing is not required for im- 'water to prevent hardening of the paint In practice the paint is supplied tothe reservoir or container 19 and the machine is trundled over the surface upon which it is required to paint a line, and by properly manipulating the rod 22 the valve 21 may be operated to control the supply of paint to the brush 18, and as the machine is propelled over the surface the brush! 18 applies the paint to the predetermined line;

That is claimed is: 1. A machme for painting a line upon the surface of a highway or street, the same comprising a supporting frame, a reservoir mounted thereon and adapted to hold the paint, a rotary brush, means for supplying paint to the brush from the said reservoir and means for applying rotary motion to the brush, and a drip catcher associated with the brush for receiving surplus paint.

2 A machine for painting a line upon the surface of a highway or. street, the same paint, a rotary brush, means for supplying paint to the brush from the said reservoir and means for applying rotary-motion to the brush, and a smoothing brush operating in the rear of the line painting brush.

3. A line painting machine, compris ing a supporting frame, a reservoir mourfted thereon to hold the paint a rotary brush, plates on the two sides of the brush to prevent spreading thereof, a valved pipe for supplying paint to the upper side of the brush from the reservoir, and a drip receptacle for surplus paint supported bysaid plates.

4:. A line painting machine, comprising a supporting frame, a reservoir mounted thereon to hold the paint, a rotary brush,

plates on the two sides of the brush to com press it, a valved pipe for supplying paint to the upper side of the brush from the reservoir, a drip receptacle forsurplus paint supported by said plates, and a. resiliently supported smoothing brush in the rear of the rotary brush. I r

In testimony whereof I aflix my signature.
